[0002] Steel pipe welding refers to the process of bending steel plates or steel strips into round, square and other shapes, and then welding them to finally form a steel pipe with a seam on the surface. This type of steel pipe is widely used in various fields, such as oil drilling, machinery manufacturing, etc. Steel pipe ring welding is a connection method that welds steel pipes in a ring shape. This welding method is widely used in oil and natural gas transportation projects. Because the annular weld accounts for a high proportion of all pipelines, it has a significant impact on the safe operation of the pipeline.

[0003] During the process of circumferential welding of steel pipes, the steel pipes need to be rotated. When the steel pipes are rotated, if the rotation speed is unstable, it may easily lead to uneven welding of the steel pipes, resulting in local weakness of the welding of the steel pipes, and may easily cause unstable connection of the steel pipes and breakage of the steel pipes, thus affecting the use of the steel pipes.

[0004] To this end, the utility model provides a steel pipe welding device. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Specific examples are given below.

[0023] like Figure 1 to Figure 2As shown, a steel pipe welding device described in an embodiment of the utility model comprises a support seat 1; a guide groove 2 is provided inside the support seat 1; a sliding frame 4 is fixedly connected to the top of the support seat 1; a rotating roller 3 is rotatably connected inside the guide groove 2, and the rotating roller 3 is symmetrically arranged inside the guide groove 2; a sliding plate 5 is slidably connected inside the sliding frame 4; an electric push rod is installed on the top of the sliding frame 4, and a pushing rod 6 is fixedly connected to the output end of the electric push rod; a sliding plate 5 is fixedly connected to the bottom of the pushing rod 6; a rotating shaft 7 is rotatably connected inside the sliding plate 5; a pushing wheel 8 is fixedly connected to the rotating shaft 7; an anti-scalding groove 9 is provided inside the guide groove 2, and the anti-scalding groove 9 is arranged at a position corresponding to the middle of the guide groove 2; a support frame 10 is fixedly connected to the top of the support seat 1; the support frame 10 is arranged at a position corresponding to the top of the anti-scalding groove 9; the support frame 1 0 is provided with a supporting notch 11 inside; during operation, when it is necessary to weld the steel pipes, the two steel pipes can be placed at the positions corresponding to the two ends of the guide groove 2, and then the sliding plate 5 can be pushed down by the electric push rod, so that the pushing wheel 8 is pressed on the top of the steel pipe, and then the pushing wheel 8 can be controlled to rotate, so that the pushing wheel 8 pushes the steel pipe to the position of the anti-scalding groove 9, so that the joint of the two steel pipes stays at the position corresponding to the anti-scalding groove 9, and then the welding gun can be passed through the supporting notch 11 to weld the steel pipe. The restriction of the supporting notch 11 can make the welding gun more stable. During the welding process, the rotating roller 3 can be controlled to rotate so that the two rotating rollers 3 rotate in the same direction, driving the steel pipe to rotate inside the guide groove 2, so that the steel pipe can be circumferentially welded. By rotating the rotating roller 3 at a uniform speed, the rotation speed of the steel pipe can be more stable during welding, so that the welding effect of the steel pipe is better.

[0024] like Figures 2 to 3 As shown, the internal rotation of the driving wheel 8 is connected with a rotating wheel 12; the rotating wheels 12 are arranged in a ring array inside the driving wheel 8 in multiple groups, and each group of rotating wheels 12 is respectively arranged inside the driving wheel 8 at the positions corresponding to the two ends of the driving wheel 8; a synchronous belt 13 is connected between each group of the driving wheels 8; during operation, when the driving wheel 8 rotates to push the steel pipe, the rotation direction of the driving wheel 8 is perpendicular to the rotation direction of the rotating wheel 12, so that the rotating wheel 12 will not affect the pushing effect of the driving wheel 8. After the driving wheel 8 has pushed the steel pipe, when the rotating roller 3 drives the steel pipe to rotate, the synchronous belt 13 is in contact with the steel pipe, so that the steel pipe is less in contact with the driving wheel 8 during the rotation process, so that the wear between the steel pipe and the driving wheel 8 is less.

[0025] like Figure 1 to Figure 2As shown, a positioning rod 14 is fixed to the top of the sliding plate 5; the positioning rod 14 is arranged in parallel with the pushing rod 6; the positioning rod 14 is slidably connected to the internal position of the sliding frame 4; during operation, when the sliding plate 5 slides inside the sliding frame 4, the sliding of the positioning rod 14 is restricted by the sliding frame 4, so that the sliding plate 5 is less likely to tilt when sliding, and the sliding of the sliding plate 5 is more stable.

[0026] like Figure 3 As shown, an anti-skid pad 15 is fixedly connected to the side wall of the synchronous belt 13; the anti-skid pad 15 is arranged at a side position of the synchronous belt 13 close to the outer side of the driving wheel 8; when working, when the synchronous belt 13 fits with the surface of the steel pipe, by arranging the anti-skid pad 15 on the synchronous belt 13, the contact area between the synchronous belt 13 and the steel pipe can be made larger, so that the synchronous belt 13 can be less likely to slip when fitting with the steel pipe.

[0027] like Figure 4 As shown, a positioning block 16 is fixedly connected to the end of the rotating shaft of the rotating roller 3; the positioning block 16 is rotatably connected to the internal position of the support seat 1; during operation, when the rotating roller 3 rotates inside the support seat 1, by restricting the positioning block 16 on the support seat 1, the rotating roller 3 is less likely to tilt during rotation, and the rotation of the rotating roller 3 is more stable.

[0028] like Figure 4 As shown, a plurality of anti-wear balls 17 are arranged between the support seat 1 and the positioning block 16; the side walls of the anti-wear balls 17 are in contact with the side walls of the support seat 1 and the positioning block 16; during operation, when the positioning block 16 rotates inside the support seat 1, by arranging the anti-wear balls 17 between the support seat 1 and the positioning block 16, the sliding friction between the support seat 1 and the positioning block 16 can be converted into rolling friction, which can make the friction force between the support seat 1 and the positioning block 16 smaller, thereby reducing the wear between the support seat 1 and the positioning block 16.

[0029] During operation, when it is necessary to weld the steel pipes, the two steel pipes can be placed at the positions corresponding to the two ends of the guide groove 2, and then the sliding plate 5 can be pushed down by the electric push rod, so that the pushing wheel 8 is pressed on the top of the steel pipe, and then the pushing wheel 8 can be controlled to rotate, so that the pushing wheel 8 pushes the steel pipe to the position of the anti-scalding groove 9, so that the joint of the two steel pipes stays at the position corresponding to the anti-scalding groove 9, and then the welding gun can be passed through the support groove 11 to weld the steel pipe. The restriction of the support groove 11 can make the welding gun more stable. During the welding process, the rotating roller 3 can be controlled to rotate so that the two rotating rollers 3 rotate in the same direction, driving the steel pipe to rotate inside the guide groove 2, so that the steel pipe can be circumferentially welded. By rotating the rotating roller 3 at a uniform speed, the rotation speed of the steel pipe can be more stable during welding, so that the welding effect of the steel pipe is better.

[0030] When the pushing wheel 8 rotates to push the steel pipe, the rotation direction of the pushing wheel 8 is set perpendicular to the rotation direction of the rotating wheel 12, so that the rotating wheel 12 will not affect the pushing effect of the pushing wheel 8. After the pushing wheel 8 has pushed the steel pipe, when the rotating roller 3 drives the steel pipe to rotate, the synchronous belt 13 is in contact with the steel pipe, so that the steel pipe is less in contact with the pushing wheel 8 during the rotation process, so that the wear between the steel pipe and the pushing wheel 8 is less.

[0031] When the sliding plate 5 slides inside the sliding frame 4, the sliding frame 4 restricts the sliding of the positioning rod 14, so that the sliding plate 5 is less likely to tilt during sliding, and the sliding of the sliding plate 5 is more stable.

[0032] When the synchronous belt 13 is in contact with the surface of the steel pipe, an anti-skid pad 15 is provided on the synchronous belt 13 to increase the contact area between the synchronous belt 13 and the steel pipe, thereby reducing the chance of slipping when the synchronous belt 13 is in contact with the steel pipe.

[0033] When the rotating roller 3 rotates inside the support seat 1 , by limiting the positioning block 16 on the support seat 1 , the rotating roller 3 is less likely to tilt during rotation, and the rotation of the rotating roller 3 is more stable.

[0034] When the positioning block 16 rotates inside the support seat 1, by arranging anti-wear balls 17 between the support seat 1 and the positioning block 16, the sliding friction between the support seat 1 and the positioning block 16 can be converted into rolling friction, which can make the friction force between the support seat 1 and the positioning block 16 smaller, thereby reducing the wear between the support seat 1 and the positioning block 16.
